Personally, I believe that in the world of cryptocurrencies, transaction costs are a fundamental aspect in determining which is more practical for everyday payments. In my opinion, Solana generally offers lower transaction fees compared to Bitcoin Cash. This is because Solana uses high-speed technology and a fee structure that favors microtransactions, making it very attractive to those looking for fast and inexpensive payments. On the other hand, Bitcoin Cash was created specifically to improve scalability and reduce costs compared to Bitcoin, but in practice, it can still have slightly higher fees during periods of congestion. In short, for everyday and frequent payments, Solana is usually cheaper and more efficient in terms of fees. However, other factors such as the acceptance, security, and liquidity of each cryptocurrency should always be considered.
